GutsRaina wakes up one night with a terrible upset stomach. Her mum has one too, so it's probably just a bug. Raina eventually returns to school, where she's dealing with the usual highs and lows: friends, not friends and classmates who think the school year is just one long gross out session. It soon becomes clear that Raina's tummy trouble isn't going away, and it coincides with her worries about food, school, and changing friendships. What's going on?
